Retinoids are the best studied ingredients for skin aging, and a systematic review supports topical tretinoin as an effective treatment for photoaging. But they can cause dryness, peeling, and stinging, and topical retinoids are contraindicated in pregnancy. That leaves many people looking for something gentler.
Several alternatives have clinical studies behind them, although none has as much evidence as retinoids. We ranked 7 retinol alternatives by evidence, results, gentleness, and suitability during pregnancy.
Retinol Alternatives Compared
| Rank | Alternative | Best evidence | Best for | Gentleness | Pregnancy |
|---|---|---|---|---|---|
| 1 | Niacinamide | 12 week study | Fine lines, spots, redness | Very gentle | Generally considered safe |
| 2 | Bakuchiol | 12 week trial vs retinol | Wrinkles, dark spots | Very gentle | Not well studied |
| 3 | Vitamin C | 6 month trial | Sun damage | Can sting | Generally considered safe |
| 4 | Signal peptides | 12 week trial | Fine lines | Very gentle | Not studied |
| 5 | Azelaic acid | Pigmentation and acne studies | Uneven tone, melasma | Mild tingling | First line for melasma |
| 6 | GHK-Cu | 12 week studies | Firmness, fine lines | Very gentle | Not studied |
| 7 | Rosehip oil | Mostly lab studies | Dry skin | Gentle | Limited data |
Full Reviews
1. Niacinamide: Best overall alternative
Niacinamide is a form of vitamin B3. In a 12 week study, topical niacinamide produced reductions in fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin yellowing, along with improved elasticity. It is gentle, inexpensive, and, together with vitamin C, considered generally safe for use in pregnancy, although large studies in pregnant women have not been done.
Not for: anyone expecting results as strong as prescription retinoids.
Our score breakdown: Evidence 6, Results 6, Gentleness 9, Pregnancy suitability 8.
2. Bakuchiol: Closest to retinol
Bakuchiol is a plant compound often called a natural retinol. In a 12 week randomized, double blind trial of 44 people, bakuchiol and retinol both significantly decreased wrinkle surface area and hyperpigmentation, with no statistical difference between them, and retinol users reported more scaling and stinging. It is a single small trial, and bakuchiol's safety in pregnancy has not been well studied, despite how it is often marketed.
Not for: anyone wanting a proven pregnancy safe option, or those with a sensitivity to plant extracts.
Our score breakdown: Evidence 6, Results 8, Gentleness 9, Pregnancy suitability 5.
3. Vitamin C: Best for sun damage
Vitamin C is an antioxidant that supports collagen. In a 6 month double blind trial, a 5% vitamin C cream led to a significant improvement in photoaged skin compared with placebo, with smoother skin relief and fewer deep furrows. Pure vitamin C is acidic and can sting, so it is usually applied in the morning under sunscreen.
Not for: very sensitive skin that reacts to acidic products.
Our score breakdown: Evidence 6, Results 6, Gentleness 6, Pregnancy suitability 8.
4. Signal Peptides: Gentlest option
Signal peptides such as palmitoyl pentapeptide, sold as Matrixyl, are designed to encourage collagen production. In a 12 week placebo controlled study of 93 women, a palmitoyl pentapeptide moisturizer was well tolerated and significantly reduced wrinkles and fine lines. Peptides are among the gentlest anti aging ingredients. The wider range of options is compared in the best peptides for skin.
Not for: anyone wanting a pregnancy tested option, since peptides have not been studied in pregnancy.
Our score breakdown: Evidence 5, Results 5, Gentleness 10, Pregnancy suitability 5.
5. Azelaic Acid: Best pregnancy safe pick
Azelaic acid is best known for acne and uneven skin tone. A 2026 review lists it as a first line treatment for melasma during pregnancy, with no adverse effects reported in animal studies. It is not a direct wrinkle treatment, but it suits people whose main concerns are dark spots, redness, or breakouts.
Not for: anyone whose main goal is reducing deep wrinkles.
Our score breakdown: Evidence 4, Results 5, Gentleness 7, Pregnancy suitability 9.
6. GHK-Cu: Best gentle prescription option
GHK-Cu is a copper peptide that supports collagen. In 12 week studies, GHK-Cu creams improved skin laxity, clarity, and firmness and reduced fine lines and wrinkles. It is well tolerated by sensitive skin but has not been studied in pregnancy, so it is not a pregnancy safe alternative. A prescription GHK-Cu cream is available after a clinician review, and more on GHK-Cu skin benefits covers what the research shows.
Not for: pregnancy or breastfeeding, or anyone with a copper sensitivity.
Our score breakdown: Evidence 5, Results 6, Gentleness 9, Pregnancy suitability 3.
7. Rosehip Oil: Weakest evidence
Rosehip oil is often promoted as a natural retinol because rosehips contain vitamins and fatty acids. A 2024 review describes rosehip extracts and oils being studied for scarring, anti aging, and hyperpigmentation, but most of the evidence comes from lab work and small studies. It is a pleasant moisturizer for dry skin rather than a proven wrinkle treatment.
Not for: anyone expecting retinol level results.
Our score breakdown: Evidence 2, Results 3, Gentleness 8, Pregnancy suitability 6.
Pregnancy Safe Retinol Alternatives
Topical retinoids and hydroquinone are contraindicated in pregnancy. Azelaic acid, vitamin C, and niacinamide are generally considered safe, while bakuchiol, peptides, and GHK-Cu have not been well studied in pregnant women. Daily sunscreen is one of the most effective and safest anti aging steps at any stage. Always check with your doctor before starting a new active ingredient while pregnant or breastfeeding.
Plant Based and Natural Retinol Alternatives
Bakuchiol is the best studied plant based alternative and the only one with a head to head trial against retinol. Rosehip oil is popular but has limited clinical evidence. Niacinamide and vitamin C are vitamins rather than plant extracts, but they are gentle and widely available.
How to Build a Routine Without Retinol
- Morning: gentle cleanser, vitamin C serum, moisturizer, sunscreen.
- Evening: gentle cleanser, a bakuchiol, peptide, or copper peptide serum, then niacinamide and moisturizer.
- Spacing: keep copper peptides away from vitamin C and strong acids, as explained in this rating of what not to mix with copper peptides.
- Patience: most studies measured results at 12 weeks or longer.
If you can tolerate a retinoid outside pregnancy, a prescription option may still give the strongest results, and the best prescription retinoid creams compare the main choices.
What the Evidence Does and Does Not Support
The evidence supports niacinamide, bakuchiol, vitamin C, and signal peptides as gentler options that can improve fine lines and tone over about 12 weeks. None has as much evidence as prescription retinoids. Pregnancy safety data are limited for every ingredient, and only azelaic acid, vitamin C, and niacinamide are generally considered safe. Most studies are small, and several were run by ingredient manufacturers.
